A print wheel is disclosed which is provided with two characters on the end of each petal. With two rows of characters on the print wheel the characters must be arranged so that only one character strikes the platen at a time with acceptably even pressure. To ensure that the entire surface of a print character strikes the platen with acceptably even pressure, the characters on the end of the petals of a daisy-wheel-type printer must be at the proper angle. With two rows of characters, the problem is doubled. When one character strikes the platen, the other, which is below it, must not. The character-carrying areas of the two rows are arranged at an angle of about 3-5 degrees to each other. The main plane of one of these character-carrying areas therefore does not coincide with the rotational plane of the print wheel.
